mx-Wmmme mAcHiNE.

T o' allI Vwhom it may conce 'n i Be it known that I, O'r'ro Pn'rnaamxn, a citizen of the Republic of Switzerland,- and i -a' resident of Groton, county of Tompkins,

'the ca'rriage again. fed one or more Spaces i and State of New, York,`` have invented cer-' tain new andv useful Improve'ments in Type- 'riting` Machines, of I which 'the :following 4 is a full, clea'r; lvand. exact description.

This' invention.` 'relates more particularly i to`V` the line-lock mechamsm and means forI stoping the carriage.

tion is' to' provide simple and 'eificient 'means ,iwhereby the carriagemaybe fed for letter Is aeing m'the usual way' and at'the endlof til eiline positively looked' against movement and 'suchfvlocking mechanlsm 'released and for the purpose of adding an`.addtional letter or letters at the' end of a line and then -yagain positively Ylooked 'against further movement.

Another object o'f the' l'nvention is to prof vide a line-lock. mechanism which comprises but few 'parts and in which a single element forms a direct -loc'k between the carria ge and a part of the mechanism actuated as thekeys 'are depressed. v t 'A further object of the mventioniis to pro- I'videa simple andfefficient device which is movable withthe carria-ge andr which operates the line-lock lever. 4

A still-further. object of the invention is 'to provide simple and efficient'. means mounted on 'the carriage and which may be utilized` as positive stops to'lock the carriage in its movement in either direction.

lVith these and other objects in view, the

'invention' will be hereinafter more particularly described with reference to the accomf 4 t pahying-drawings,- which form a part of this specification, and -will then be pointed out t in the'claims at the end of the description.I

In the dra-Wings, Figure 1 is a longitudinal section of one form of typewriting ma- 'chine showing` one embodiment of my invention` applied thereto.`

pluralit v of characters th zreon and which is adapted to be forced as e: ch key-lever is de'- pressed against the work sheet on the platen The platen 22.'is mounted upon the carrlage :33 whichis adapted to travel back and lforth on the carrlage bed 21 'there bem suitable letter-spacing 'nr :c'ha nism providec said universal bar is adaJted to be engaged by a; tongue or projecticn- 27 of 'each keylever. The universalJar is provided' With npward'ly'extendmg arms 28 and these arms are 3ivot'ally connected to the arms-29 of bell-crank levers -30, there'being a bell-'crauk lever and a universal bhr'afm 28 at each side of the machine.-l lflach', bell-crank leverlhs pivoted at 31 and has one arm, as extending verticallf,y and said arms 32 are con- 1. cted together by a transversel)Y extending .ro\d 33. This rod 33"passes throughslots :Sl

of upright rocking arms 13.5. yThe arms moved by its' link 1.8 and at the same time i the tongue 27 ofeach key-lever Will engage the universal bar so as to rock the bell-cranks 30 on theirpivots. As the bell-crank levers are rocked. the rod33 vvill rock the arms 35 and consequentlv move the har 37 and cause the tappet 38 t'o engagethe dog carrier andtherebv permit the carriage to move a single space. The arms 3-5 and the bar 37 form a universal bar or rocking frame and saidframe as vvell as the other parts thus far described, ma v be of the usual or' of an7 prep ferred Construction.

A lever 39 is pivoted at face of the bed 24 and is normall)Y forced against a stop ll byv a spring 42. The for- Ward'V end of the lever 39 is bent dovvnvvard, as at 13, and is adapted to be moved into the path of a tappetor projection at carried b v the transverse baixl? of the rocking frame. 'hen the lever 39 is movedinto the path of the projection ll as will be hereinafter described` the bar, 37 as ivell as the entire rocking frame ivillbe preventral from being moved bv the writing or spacing levers and consequently the said levers cannot be depressed. p

To mov'e the lever 39 on its pivot as the carri-age is forced along its bed. a device 45 is provided. This device is mounted upon a bar 4,6 ivhich is pivotallv held to the carriage frame at the' rear of the platcn 22; The har 16 is normalllv forced'in one direction bv a spring i? to force the device 45 into position to engage a part of the lever 35) as the carriage moves along its bed and approaches the end of a line. The har -lt has one end projecting through one end of the carriage frame and held' to said bar is a lever 48. The lever 4-8 has amextcnsion l) i with one end bent invvard to engage one edge of the carriage frame and at its other end extends forward andis provided with a fin-j 40 to the under ger piece or key 50. As the ke)Y :30 `is 'depressed, the 'lever '-18 Will tilt-the bar [4:6 and Will thereby move the device st away from the 'outer end of the lever 39 to permit further movement of l-tl-- carriage after -it has once been looked. The device -15 has apendent arm 51 and this arm is adapted to engage either of the fingers orfprojections 52 or of the lev'er 39. the said-fingers being spaced apart anjv suitable distance so that the pendent arm 51 ivill first engage the projection 52 and after being released will engage on further movement of the carriage the projection or finger 53. lt vvill thus be evident that as the carria-ge moves along its bed. the pendent arm 51 bv engagement ivith the projection 52 Will. force the end .-l3 of the lever 39 into the pathof movement of the path of the projection LHof the universal bar frame, thus again lockin-g said frame and key-levers against movement. lt ivill he seen, therefore, that oneor more characters may -be added to the end of the line if desired and the carriage locked against'furthen movement.

The member or device 45 maybe variouslv constructed. s shovvn it comprises t\vo members 54 and The looking member 54 is provided ivith a head 5G and the guiding member 55 With a head -These members are made of lflat sheet metal formed bv (lies or 'otherwise and the heads 56 and 57 are substantially U-shaped in plan and one head'fits Within the other in such a vvalv as to permit relative movement. The head 57 may be called the guiding head for 'the device and the head 56 the looking head. The bar 46 has a pluralitiY of verticallv extending slots 57=l spaced apart and adapted to eni said slot-sis a dog or tooth 58 of the head 56. The guiding head 57 is provided With openings through the side platcs or vvalls 59 of substantiallv the same size and shape as the bar +16 in order that it mav he properly guided along the bar 4-6. and the head has an opening longer than the bar 46 on the side or ivall G0 onl v. The side ('1 of the head 56 is relativelv Shorter thanthc Side (30 and permits said' head 5G to spa n the hcad'T so as to be guided properly therebv. The head 56 has a pendent part or' arm (3:2 which'is secured to the pendent part or arm place, the end 4:3 is again. moved |into the 4 ipimeeo '5'1 and 62 and extends upn'in'd hctween the heads 56 and 'iand normally forces one of the hei'lds along the other and normally Lis causes the dog or tooth 58 to engage one of theslots of the ha'r 46 and be lield t'o said bar lGin on'e of its adjustments. The head 56 'is roughened to provide a finger surfacel 65 so that by pressingawith the finger on the 4head 56, the tooth 58 may be disengaged from one of the slots 57at and the entire devi'ce Inovedvalong the har 46, and on releas- 'ing the head 56 of any rpressure hy the finger, tlie device Willbe locked to tlie bar in any desired position. W In this Way the carriage may he,locked at' various points Vhy simply adjusting the device 45'.

A device 66,is located at' the opposite end `of the har atand is similarly constructed'to the' device 45'. A third device 66?d is arranged on the bar 4:6 intermediate the devices 45, and 66,'and said device 66-1 is adjustable on said bar Vand Vis located on the same sideV ofthe4 machine as the device 66. The device `6Ga is similarly constructed; to the other devices :except tliat the pendent arin i. 'fiat spring 64 is interposed lbetween 'thaarius or parts or part 51 not so long as in the devices 45.

and GG and may he only of a length corres sponding to tlie 'arm or part'62.;' The stop -Gfifl acts as a 'regularstop for a' plain margin Iand stop GG is a special additional margin stop which might be adjusted to any suitable distance from tlie stop 66%.

It will-'he evident thatV if the carriage is moved backivard in the usual way until the stop (S69 engages the p'rojection 67 onithe bracket 68 the usual degree of margin may be secured.

If. hoivever, the har i? is movedby operating the finger lever lS, the stop'fifia' may be released from the projection G7 -and the carriage given-a furtherI backward inovefl ment' until the' arm 51 of the'device 66 engag'es; the stop or projection G7. If an additional margin isl desired, the device 66' may bereleased from the projection GT and the carriage nioved still fartlierbackivai'd until the a'rm 51 of the device G6 engagesthe projection 'oififinger 53 |of the lever 39 which forms a stop for tliearin Til. If the carriage is nioved the latter distance, that is.- until the arin 51 of the device (3G engages the finger -of the lever the machine may be operated in the usual way for letter writing and as the carriage moves toward the left oi' adjustmcnts for the writingl of notes, etc., or
